Federal agents descended on former President Donald Trump's Mar-a-Lago home Monday in Palm Beach, Florida, as part of an investigation into allegations he took classified records from the White House and stored them at the home for up to a year, a potentially serious violation of the law. Experts, including a presidential historian and former FBI leader, called the search "unprecedented" and a "big deal." Trump denounced the investigation, saying he was entitled to take the records, which could include documents from appointments and call logs to handwritten notes. Here's a timeline from @usatodaygraphics of the investigation into the former president's handling of presidential records. Read the full timeline at the link in our bio. Since 2021, Trump has faced legal scrutiny in at least five independent federal and state inquiries that are both criminal and civil in nature. At least two investigations involve the 2020 election. A bipartisan House committee is digging into Trump's role in the Jan. 6 Capitol attack. New York's attorney general is investigating the Trump Organization's business practices. And a federal inquiry into presidential records is ongoing, and appears to have prompted a search by the FBI at his Florida estate. The latest action prompted Trump to make accusations of a "witch hunt" in all levels of government, including the bureau itself. However, FBI director Christopher Wray was appointed by Trump, while he was president.
